Three capacitors are connected as follows: 3.64 F capacitor and 4.67 F capacitor are connected in series, then that combination is connected in parallel with a capacitor of 7.16 F. What is the capacitance of the total combination?

First, let's find the equivalent capacitance of the capacitors connected in series.

We can find it using the following formula:


\begin{gathered} (1)/(Ceq1)=(1)/(C1)+(1)/(C2) \\ so: \\ (1)/(Ceq1)=(1)/(3.64)+(1)/(4.67) \\ Ceq1=2.05F \end{gathered}

Now we can find the equivalent capacitance of the capacitors connected in parallel using the following formula:


\begin{gathered} C_(eq)=Ceq1+C3 \\ C_(eq)=2.05F+7.16F \\ C_(eq)\approx9.21F \end{gathered}

Answer:

9.21 F
